> Consumer drives ... and rarely for more than 3 years of warranty.

Looking at my list of consumer SSDs and their warranties:

Samsung EVO 850: 2y

Samsung EVO 960: 3y

Samsung EVO 860: 5y

Samsung EVO 970: 5y

Samsung PRO 970: 5y

For comparison with spinning rust HDDs:

Seagate Ironwolf: 3y

WD Red (both EFAX & EFRX): 3y

But take a wider sample of consumer SSDs, a large majority are <=3 years. And look at enterprise SSDs.

Seagate Ironwolf and WD Red are not enterprise spinny hard disk drives, instead look at Seagate X18 or WD HC560.

Yes, I know, I was comparing warranty on consumer SSDs and consumer HDDs.

Consumer drives usually exclude wear out in their warranties making the number of years pretty much irrelevant. What is does show is that vendors are more confidence in their FTLs and hardware nowadays compared to the first high volume SSDs on the market more than a decade ago.
